That is the exact card I bought, I paid for the 2gb version but for some reason dxdiag, system, and other places say I have 4033mb of "approx. total memory".

Very confused, mostly because I want to buy another for SLI and I'm not sure if I should buy the 2 or the 4gb card? Please help! 😀

Thanks in advance

I think that is just Windows DX reporting the VRAM plus the system RAM and the address space set aside for the card. Run GPU-Z and have it check for you.
